【摘要】：采用兩步法成功制備了新型鈦鎳合金Ti Ni45V8In0.2,并進行XRD、SEM以及力學性能、抗應力松弛性能和耐腐蝕性能的測試與分析。結果表明:該新型合金由網(wǎng)狀Ti Ni母相和彌散分布的V3Ni相組成,具有較佳的力學性能、抗應力松弛性能和耐腐蝕性能。與常規(guī)Ti Ni合金相比,新型合金的-40、25℃和150℃抗拉強度分別增加47.1%、39.4%、123.9%;-40、25℃和150℃屈服強度分別增加110.3%、92.5%、263.8%;腐蝕電位正移267 m V;50 h后的應力松弛從16%減小至0.5%。
[Abstract]:A new Ti-Ni alloy Ti Ni 45V 8in 0.2 was successfully prepared by two-step method. The mechanical properties, stress relaxation and corrosion resistance of the alloy were measured and analyzed. The results show that the new alloy consists of a network Ti-Ni master phase and a dispersed V3Ni phase. It has better mechanical properties, stress relaxation resistance and corrosion resistance. The tensile strength of the new alloy increases by 47.1 鈩，
